could be anything.start by pulling fuses and watching your meter.are you letting the car go to sleep before assuming you have a draw? if you are letting the car go to sleep,hop inside the car,close the door,let it die down and pull fuses 1 at a time.as soon as you see the meter drop,the fuse you pulled is the circuit that's pulling down the battery.

make sure you wait 20 minutes for your cars computer to go into sleep mode... then get your reading.. i got my reading at 25 milli amps (.025 amps).. your reading is still too high... get the car in sleep mode

I've got an electronics degree, BSEE, and 200ma = 0.2 amps ;
20ma = .02a ( to convert from ma to amps move the decimal point THREE places to the left; to go from a to ma move the decimal point THREE places to the right).

At rest, aproximately 7-10 min after you shut the car off, you should be drawing aprox 20 to 25 ma. If you are really drawing 200 ma (0.2a ) you've got something running that shouldn't be running.
